Despite an onslaught of scrutiny and scandal over the past few years, Facebook closed out the second decade of the millennium stronger than ever, Axios' Sara Fischer reports.

• The tech giant brought in nearly $70 billion in revenue for 2019, up more than 25% from the year before — and up more than 1,300% from 2012, the year it went public.
• For the past several quarters, Facebook has warned investors that it expects revenue headwinds in light of increased regulatory scrutiny, particularly around privacy and targeted advertising.

Why it matters: Facebook's continued ability to post double-digit revenue growth every year shows how well it has been able to innovate and adapt.

• Case in point: Even in regions like North America and Europe, where the company's user growth has plateaued and privacy regulation has been introduced, Facebook has still managed to squeeze significantly more money out of each user every year.
• In the U.S. and Canada, Facebook has increased its user base by less than 4% in the past two years — but it has increased its revenue per user there by more than 60%.

The bottom line: Facebook recognizes that there's a gulf between its prodigious growth and its beleaguered reputation. On an investor call following Facebook's earnings report Wednesday, CEO Mark Zuckerberg said:

We're focused on communicating more clearly about what we stand for. One critique of our approach for much of the last decade is that because we wanted to be liked, we didn't want to communicate our views as clearly, because we worried about offending people. ... Our goal for the next decade isn't to be liked, but understood. In order to be trusted, people need to know what we stand for.

As the Senate prepares for a second long day of Q&A, Republicans seem increasingly confident that at least 51 senators will vote tomorrow to prevent witnesses at President Trump’s impeachment trial, Axios' Alayna Treene reports.

• The whip count is still fluid, but GOP senators are far more optimistic after yesterday's eight-hour session than they were following their closed-door meeting on Tuesday.

What we're hearing: Tuesday evening's meeting was strategically timed — and played the role that Republican leaders had hoped it would.

• Sources familiar with the meeting tell Axios that Senate Majority Leader Mitch McConnell told his conference that he did not yet have the votes to block witnesses — knowing that the news would likely leak to the media, and alarm some senators who dread both a prolonged impeachment trial and Trump's Twitter wrath.
• McConnell and Majority Whip John Thune thought addressing the conference in a secretive setting would dial up the pressure.

What Republicans up for re-election this year are saying:

• Sen. Martha McSally (Ariz.): "I have heard enough. It is time to vote."
• Sen. Cory Gardner (Colo.): "I do not believe we need to hear from an 18th witness."
• Sen. Pat Toomey (Pa.): "I’m very, very skeptical that ... criteria is going to be met" to call more witnesses.

Go deeper: Highlights from yesterday's Q&A session.

On average, an infant born in 2018 is expected to live about 78 years and 8 months, the CDC says in a report out today.

• Women still live longer: For males, it's about 76 years and 2 months. For females, 81 years and 1 month.

Why it matters: The rise is due to lower death rates for cancer and drug overdoses.

Berkshire Hathaway, the corporate holding company owned mostly by billionaire Warren Buffett, will sell its newspaper operations to publisher Lee Enterprises Inc. for $140 million.

Why it matters, via Axios' Sara Fischer: Buffett loves the newspaper business. His first job was a newspaper delivery boy for the Washington Post — and he has long been a vocal supporter of local news.

• The fact that he is finally giving up on the industry, which he has warned in recent years is "toast" due to terminal advertising decline, is significant and symbolic.

D.C. Mayor Muriel Bowser will proclaim today Gwen Ifill Day at a U.S. Postal Service ceremony for the issue of a Forever stamp (always good, even when rates rise) honoring the pioneering journalist as part of the Black Heritage series.

• USPS says the news will be shared with #GwenIfillForever.

Ifill — an inspiration as she rose to the heights of journalism as a political reporter for the Washington Post, New York Times and NBC News — was co-anchor or "PBS NewsHour" when she died of cancer at 61 in 2016.

• From her N.Y. Times obituary: "Ifill was in the forefront of a journalism vanguard as a black woman in a field dominated by white men."
